ISL32175EIVZ-T

Overview

The ISL32175EIVZ-T is a quad receiver RS-422/RS-485 interface integrated circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3V to 5.5V and supports data rates up to 80Mbps. The device features a 30mV receiver hysteresis for noise immunity and includes ±15kV ESD protection on the bus lines. Designed for surface-mount applications, it is housed in a 16-pin TSSOP package with a width of 4.40mm. The component functions reliably across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Provides four independent receivers compliant with RS-422 and RS-485 standards
• Integrates high-voltage electrostatic discharge protection on all bus pins
• Utilizes low hysteresis design to enhance signal integrity in noisy environments

Applications

• Industrial control systems requiring robust serial communication
• Building automation networks utilizing RS-485 multipoint topology
• Data acquisition modules operating in electrically harsh environments

Procurement Notes

Verify the specific suffix IVZ-T against official Renesas documentation to confirm the TSSOP-16 package and tape-and-reel shipping configuration. Ensure compatibility with RoHS3 directives and check moisture sensitivity level classifications prior to soldering. Confirm availability status as distribution listings may vary.

Selection Notes

Select this component when a design requires only receiving capabilities rather than full transceiver functionality. The wide operating temperature range makes it suitable for demanding industrial settings. Verify that the 80Mbps speed meets system requirements and that the 3V to 5.5V supply aligns with the target logic levels.

Part Context

This part belongs to the ISL32x75E series of RS-485/RS-422 receivers. It shares architectural similarities with other members like the ISL32173E but differs in pin count and channel configuration. The series is characterized by high-speed operation and robust ESD protection, targeting reliable data transmission in industrial and commercial applications.

Replacement Considerations

Check for direct pin-compatible alternatives within the same Renesas family. Verify if updated revisions offer improved packaging or extended longevity guarantees before sourcing substitutes.
